SPRAYING- DEVICE.

application filed May 13, 1925. seriailvo. 29,912.

The invention relates-to an improvement in spraying `devices for Washing can covers and the like.

By reason of their peculiar shape considerable dii'liculty has been experienced in etfectively cleansing the covers of the large cans used for the transportation oflluid inillr. The object of the present invention is to produce a spraying device forwashiin;r can covers and the like so constructedand arranged as to assure a rapid and thorough cleansing of the can covers or other articles. To this end the invention consists inthe improved spraying device vhereinafter described and particularly pointed out inthe claims.

ln the accompanying `drawings illustrating,l the preferred form of the invention, Fig. l is a plan view of the improved spraying device and shows its relation to thetrunway aiong which the can covers are advanced into and through the device; Fig. 2 isaside elevation, partly in section, of the spraying device shown in Fig. l; and Fig. 3 is an enlarged transverse section through a portion ot the spraying device, illustrating particularly the spray perforations.

The improved spraying device, `as illustrated in the drawings, is especially adapted tor use in cleansing can covers of the usual umbrella type, shown in sect-ion at 5 in Fin'. This can cover 5 comprises a cylindrical body'portion 6 adapted to fit `within the neclr of the usual forty quart can used for the transportation `of iiuid'mill. The

upper end of the cylindrical portion 6 of the f can cover is closed by a depressed disc portion l", the outer edges of which project `outwardly and downwardly as a curved flange or umbrella-like portion 8. Although the iilustrated embodiment of `the improved spraying device is particularly adapted for washing this type of can cover orflikeutensil, it will be understood that the invention is not to be restricted to this use, inasmuch as it is equally adapted with obvious changes for use in cleansing` various kinds of utensils.

The improved spraying device comprises a cylindrical head 10 which may conveniently be of substantially the same diameter as the can cover 5. The head l0 is a hollow structure, as indicated by the dotted lines 11 in Fig. 2, and is adapted to be supplied with water or other washing fluid under pressure '27 and 28.

through the pipe lQscrewcd into the threaded port 13. The open lower endet the hollow headlOvis-closed by a bottom cover lll. The laterally projectingtlange l5 of the headlO is provided with four bosses l which valign with four bosses 17 projecting* latei-allyffrom the rim oit the cover lf-l. The bolts 18 looselyreceived in the bosses 17 and screwed intorthe'rbosses lo secure the cover Illlto the head l0.

The upper portionwof the spray-head1() consists of twoserics ot opposed steps at various levels, `as shown in il, so as thereby to accommodate conveniently the can covers or other articles to be washed and bring the surfaces `to be cleansed relatively close to the orifices orperforations through `which the washing `fluid is ejected. The upper-steps 2O and 2l are spaced apart so that the cylindrical portion 6 yof the covers may pass freely between them. The upper surfaces of the steps `Q0 `aud 2l are provided with the perfor-ations 22 arrangedat various angles by `which the washing lluid is directed into theannular concavity under the umbrella-like portion .8 of the covers. rlhe intermediatefsteps 23 and 24 are provided `at their upper surfaces with the pert'orations 25 arranged at various angles, 'as clearly shown in Fig. 3,so thatthe wash fluid may reach the entire inner sur-faces of the cover constituted by the disc port-ion 7 and the cylindrical portion 6. f'lhe perit'orations .in the step 23 ldirect the wash fluid to Aone inner side of the can cover-aud `the pert'oi tions in the step 24- -direct the wash tluid to the other inner side `of the can cover. The steps 23and 2.4 are spaced apart to provide space for the sprays from `the anculacly arranged p'erfcrations 26 in `the bottom steps The perforations E26 .direct wash fluid only to the under surface of the disc-like portion Trot the can covers. it will be observed by reference to Fig. :2 that the pert'orations 25 and 26 are so arranged as to eltectively direct the sprays of wash iiuid against every part of the entire interior surtace of the cylindrical portion of the cover.

The can covers are successively brought to rest over the spray head l0 by means or" a cover-engaging linger 8O yieldingly mounted on an intermittently reciprocatina bar 3l located in the longitudinal recess 3a between the steps 27 and 28. The reciprocatiiul` bar 3l and linger 30 operate in the usual manner and need no further description.

The can covers are supported on the guide rails or rods 33 and 34 secured to the inner opposed faces ofthe steps 23 and 2s. The upper edges of the rods 33 and 34 are substantially flush with the upper surfaces of the steps 23 and 2s and for the purposes of this inventionV may be regarded as forming part o f the steps 23 and The covers are guided laterally by means of the rails or rods 36 and 37 secured to the inner opposed faces of the upper steps and 2l.

The improved spraying -device of the present invention is designed to constitute a unit in a series of such devices acting in conjunction and synchronously with devices arranged to wash and sterilize the insides of the cans to which the covers belong. ln practice, each cover accompanies its can through the washing apparatus so that when they emerge therefrom the operative may place each cover on its respective can.

Having thus described the invention what l claim as new is l. A spraying device for washing can covers and the like comprising, a hollow head adapted to be supplied with wash fluid under pressure, the upper portion ofv the head consisting of two series of oppositely disposed steps, the upper pair of steps being spaced apart for the passage between them of the cylindrical portion of the cover, a lower pair of stepsv being adapted to receive and support the lower edge of the cover, the
